[5] Ngata has written articles for media outlets including E-Tangata (an on-line magazine that promotes stories from a Māori and Pasifika perspective),[6] The Spinoff[7] and Pantograph Punch.
The idea that one group has a right to claim domination over another — based on supremacy of genes, skin colour, ethnicity or similar characteristics — was never a mere intellectual exercise.
In 2023 Ngata was the Activist in Residence with the Center for Culture-Centered Approach to Research & Evaluation (CARE) on anti-racism and in connection with Professor Mohan Dutta at Massey University (Manawatū campus).
[14] Anti-racist work Ngata has been involved in includes a public deputation to the Gisborne District Council in 2020 around the issue of statues related to Captain James Cook.
[18][19] Ngata speaks at many events and conferences, including in 2018 at the National Aquarium of New Zealand, Napier; this talk was with Marcus Eriksen and Anna Cummins and was about plastic pollution in the Pacific Ocean.
[23][24] Immediately after Cyclone Gabrielle, Ngata and others rallied with a successful fundraising campaign for disaster response and preparedness for the impacted communities of Matakaoa, Tokomaru, Te Puia and Waipiro Bay.
